Gas filter AP

platepressurefor the pharmaceutical industry

Autopress Autopress (type AP) is a discontinuously operating, fully automatic pressure filter with vertically arranged plate-shaped filter elements. Thanks to the perfectly closed system, even suspensions that are difficult to filter can be efficiently processed and separated in batch operation. Its mode of operation resembles that of a filter press, but the Autopress works absolutely gas tight and fully automatic, including cake discharge. The filter can be integrated with a fully tight and self-contained process (also GMP-compatible), thus also meeting requirements regarding sterility, explosion prevention, workplace safety or validation with ease. In particular media that are sterile or have to be processed in closed systems for reasons of toxicity and workplace hygiene can be separated into pure products. Benefits at a glance: • Continuous and fully automated operation • Multiple consecutive process steps • Closed, gas-tight method of production • Suitable for suspensions containing solvents • Outstanding safety and hygiene at the workplace • Validatable, suitable for pharmaceutical end products Gas-tight and self-contained filtration The filtration, and thus the cake formation, takes place on both outer sides of the filter plates. The filtrate is guided to the center of the plate through guide channels and removed via filtrate drain holes. The filter cake is normally discharged in a pre-dried state; however, it can be processed further, including washing, extraction, pressing, blowing out and drying
